In the Marvel Cinematic Universe, (specifically The Avengers and Guardians of the Galaxy), Thanos is seen in a throne floating above a desolate asteroid field.
This seems really impractical. Even though Thanos is a superpowerful being, it seems like he would want... well, stuff around him. There's nowhere for ships to arrive, for him to purchase new heralds after certain accusers kill them, for him to store any infinity gems, or to do anything but float on his throne.
Why does Thanos appear to headquarter himself in such an odd place in these movies?
